Throttlestop vs Intel XTU difference in LLC/Ring Offset?

    I have an Asus GL702VS (i7-7700hq and GTX 1070) and it runs really hot sometimes, so I like to underclock as otherwise in some games the CPU easily hits over 90 degrees Celsius. My system seems pretty stable at -100Mv.

    I've noticed in HWMonitor that when using Intel XTU when I activate the underclock, the IA Offset reads -0.102V and the LLC/Ring Offset also reads -0.102V, but when I use Throttlestop instead, in HW Monitor the IA Offset reads -0.102V but the LLC/Ring Offset says +0.0000.

    I'll be honest I don't really know what the difference and don't really understand why when using XTU and Throttlestop the values of the LLC/Ring Offset are different.

    I'm trying out Throttlestop, as no matter what I do in XTU, it doesn't always apply the underclock after a reboot, even if I set an App Profile pairing to underclock when Steam is running (which it always is, it runs on startup). Throttlestop seems to apply the underclock fine after a reboot, providing I configure it to run on startup in the Task Scheduler.

    Anyway, back to the voltages. I want my laptop to last as long as possible, so just trying to keep the heat a bit lower whilst keeping the system stable, and without too much of a performance hit. Can anyone with a bit more experience and knowledge in this area help me out please and explain why XTU changes the LLC/Ring Offset and Throttlestop doesn't? Is it important?

    Finally, one last question, is it possible to underclock from the bios? I have the latest bios version (3.07 iirc) but I can't find any details of voltages at all in the bios. Do I have to Flash a special BIOS or hit a key combination to enter engineer mode/more advanced settings?

    Thanks a lot!

    When using ThrottleStop, you need to adjust the CPU Core and CPU Cache voltage offsets individually. After applying your voltages, use the monitoring table in the top right corner of the ThrottleStop FIVR window to make sure both Core and Cache are adjusted equally. On a 7700HQ, if these two voltages are not adjusted equally, your under volt will not work.

    That is a common problem. Great program, nice colorful graphs, but very inconsistent. You have to constantly check to see if your under volt is applied or not. Get ThrottleStop setup correctly and you will not have this problem.

    If you have any more questions, there is a huge ThrottleStop thread on NBR. The link is in my signature.

    Ah so the LLC/Ring offset is the CPU Cache Voltage? Regardless, I'll read through the guides links you posted! Thanks so much for your quick response!

    I've read through these and the information is very straightforward, to the point and informative, thanks very much for the explanation and the links, I really appreciate it unclewebb! PS, great job on ThrottleStop, it's so much better than Intel's XTU now that I actually understand it, particularly as that's some pretty damn good documentation too!!

    Intel could learn a thing or two from you - there's no point having pretty graphs if the program itself isn't actually that intuitive, even after a good read, and the fact it doesn't retain it's underclock most of the time makes using throttlestop a no brainer in comparison to XTU!

    I don't even care if I can or cannot undervolt from the Bios anymore as Throttlestop does exactly what I need it to, so thanks again!

    Hello,

    I'm looking into buying the Asus Rog 702VS (75Hz version), however I read a lot about the heating issues... But, still I'm dying for a full gtx 1070 & not a Max Q one for such a great price. I read too many comments about undervolting until I reached the end & simply got lost on how to do it. If you don't mind, can you please list for me the steps that I have to do to properly undervolt (try to be simple, yet detailed)? Sorry for this, but you're the only one that can help me.

    I hope you undestand,
    Thank you!
